RELEASE: emc 2.2.6

Tags:

I'm pleased to announce the next release of the emc 2.2 series, emc
2.2.6. This version contains many bugfixes, a new unified
driver for the Mesa PCI and parport cards such as 5i20 and 7i33, and a
sample configuration for the Tormach PCNC 1100.

The new packages are now available in the package repository. If you
have already installed an earlier 2.2.x version, this is available as an
update. If you are still using 2.1.7 but want to upgrade, instructions
are here.

CVS users can get this release by checking out the RELEASE_2_2_6 tag.
Tarballs will be available on sourceforge.net within the next 24 hours.
